Here's a project where electro-magnets are used to actuate strings on a piano. http://music.ece.drexel.edu/research/mrp/actuation Unfortunately I haven't been able to find much else on the internets.

Is it possible to vibrate a string with electricity? I'm guessing an electro-magnet placed close to the string would be able to vibrate it. If the electro-magnet is used to vibrate the string, I'm guessing the electro-magnet should be pulsed at the fundamental resonate frequency of the string...

Perfect, thank you. So the first harmonic's frequency is 6.27 x the fundamental, and the second harmonic is 17.55 x the fundamental. That's definitely not "Musical" in the way strings' harmonic frequencies double the fundamental. Ruh Roh..

Thanks BvU, I'm guessing that objects are less sensitive to sympathetically resonating at higher harmonics, compared to their fundamental right? I'm trying to design a musical instrument that has solid 'tines' (these can be made of any material, and any shape) for each note that resonate...

Hi everyone, first time post here. I know (or at least think I know) that strings can sympathetically resonate at harmonic intervals. For example, a string whose fundamental is 400Hz is able to resonate at 800Hz if it's excited by a 800Hz source. Maybe I'm wrong on that as well? heh.. Anyways...
